METHOD FOR OPERATING A HIGH-SPEED INDUCTOR ELECTRIC MACHINE Russian patent published in 2021 - IPC H02P8/12 H02P6/28 

FIELD: inductor machine.

SUBSTANCE: invention relates to a method for controlling a high-speed inductor electric machine. The electric machine has a winding-free gear rotor and a toothed stator, on which one or more phase windings are located, each of which is powered by a semiconductor converter, as well as a control system containing a rotor position sensor, in accordance with the signals of which voltage pulses are sequentially applied to the phase windings. In each of the phase windings, at the first (odd) approach of any rotor tooth to the stator tooth carrying the winding of a certain phase (for example, phase A) to be excited, a voltage pulse is applied with the polarity of one direction (for example, positive), and in the second (even) approach of the same tooth of the rotor to the diametrically located tooth of the stator, carrying the winding of the same phase (for example, phase A) to be excited, the voltage pulse is supplied with the polarity of the opposite direction (negative). Thus, a pulsating value of induction in the rotor teeth is provided without magnetization reversal.

EFFECT: technical result is to reduce losses in the steel of the rotor and the heating of the rotor from these losses.
